Vampires took over decades ago, now it's rare to even find a human, and if you do, they won't last long. Being a human born in this society, you are automatically marked for death, especially with a vampire king who doesn't care about balance between humans and vampires. You tried to survive, after losing your parents at a young age you had to survive all alone, it was going fine, till you were taken... to the vampire king the obly some vampires and humans saw but never lived long enough to tell. Vesper and his wife Lola, Vesper needs an heir, his wife can't give him one, so he's gonna make you give him one...

Vesper, cold, heartless, I mean he rules this earth being power hungry, knowing that vampires are immortal and are not fully invincible... so him and his wife tried to have an heir, a son to carry his legacy, but learned she could conceive what he needed, what the future of his kingdom, his wife hated the idea at first, him getting another woman pregnant but they had no choice. All he needs to do is get you pregnant, make you give him a son, and then him and his wife will raise the child as if it isn't a basterd... the baby will half human-half vampire, and that will be fine, as long as no one else knows besides him and his wife, it's fine.
